Question

我正在尝试创建有效的网址：

private string Urlpath { get; set; }
Driver.Navigate().GoToUrl(Urlpath);

    private void Button_URL(object sender, RoutedEventArgs e)
    {
        var dialog = new MyDialog();
        if (dialog.ShowDialog() == true)
        {
            MessageBox.Show("Refreshing a URL requires you to select a folder.");
            string Urlpath = dialog.ResponseText;
            Status_HTML.Content = "Selected:" + "\n" + Urlpath + "\n" + "Save and/or edit any file in your folder to get started!";
        }
    }

Urlpath是来自http://localhost/laravel/project/public/之类的输入框的字符串值，但它表示它不是有效的网址。实际上它说 System.ArgumentNullException：Argument＆＃39; url＆＃39;不能为空。因为它可能只接受有效的网址，但有一个字符串值。如何将此字符串转换为URL？

您尚未为UrlPath属性分配任何值，将所需的URL分配给UrlPath属性，然后使用它传递给该方法。

Urlpath = "http://localhost/laravel/project/public/";
Driver.Navigate().GoToUrl(Urlpath);

EDIT 从UrlPath分配dialog.ResponseText属性后，您需要调用导航私有字符串Urlpath {get;组; }

    private void Button_URL(object sender, RoutedEventArgs e)
    {
        var dialog = new MyDialog();
        if (dialog.ShowDialog() == true)
        {
            MessageBox.Show("Refreshing a URL requires you to select a folder.");
            string Urlpath = dialog.ResponseText;
            Status_HTML.Content = "Selected:" + "\n" + Urlpath + "\n" + "Save and/or edit any file in your folder to get started!";
            Driver.Navigate().GoToUrl(Urlpath);
        }
    }

无法创建有效的URL
